Quantifying, Predicting, and Exploiting Uncertainty (QPE)

Abstract

LONG TERM GOALS. The long term goal of our QPE work is to: 1) quantitatively understand what the uncertainties are in low frequency (10-1500 Hz) acoustic propagation and noise that are caused by variable and complex oceanography and seabed structure, 2) determine the limits to predicting the fluctuating and variable propagation and noise in this frequency regime and others, and 3) ascertain what naval advantage may be gained (if any) by understanding the nature of the uncertainty. OBJECTIVES. Our (continuing) primary objectives this year were to analyze the data from the main experiment in the East China Sea in 2009, and to work towards explanations of what was observed. Particular emphasis was placed on: 1) ambient noise data analysis, and 2) the theoretical explanation of the azimuthal anisotropy of transmission loss (TL) observed.
